Which Java edition is used to build android applications?

Hi.
I am a bit confused. There are three editions of Java. They are Standard Edition, Micro Edition and Enterprise edition. The Sun certification for micro edition is titled "Sun Certified Mobile Application Developer". The name suggests that Java ME is used for building mobile applications. But When I watched some video tutorials, I saw that they used Java Standard edition for android app development.

Please kindly tell me which edition of Java is used to build android applications. Standard edition or micro edition?

The difference between Java editions has to do with the set of classes that edition is based on. The actual compilable language is the same, regardless.

The Android base class library is a stripped-down clone of the Java Standard Edition classes, but it itself is not those classes. The J2SE, J2ME and J2EE classes are all Oracle/Sun products and the Android/Dalvik classes come from Google.
